Processors of all types try to avoid generating scrap, but when it is made it generally is re-used by putting it back into the process. Production (or post-industrial) scrap includes off-spec parts, sprues, edge trim from film and sheet, and the like. It is usually reduced in size by devices such as granulators, shredders and pulverizers, and re-fed into the processing machine.
